    ABSTRACT: Being a morning person is a behavioural indicator of a person's underlying circadian rhythm. Using genome-wide data from 697,828 UK Biobank and 23andMe participants we increase the number of genetic loci associated with being a morning person from 24 to 351. Using data from 85,760 individuals with activity-monitor derived measures of sleep timing we find that the chronotype loci associate with sleep timing: the mean sleep timing of the 5% of individuals carrying the most morningness alleles is 25 min earlier than the 5% carrying the fewest. The loci are enriched for genes involved in circadian regulation, cAMP, glutamate and insulin signalling pathways, and those expressed in the retina, hindbrain, hypothalamus, and pituitary. Using Mendelian Randomisation, we show that being

    ABSTRACT: Circadian rhythms are a nearly universal feature of living organisms and affect almost every biological process. Our innate preference for mornings or evenings is determined by the phase of our circadian rhythms. We conduct a genome-wide association analysis of self-reported morningness, followed by analyses of biological pathways and related phenotypes. We identify 15 significantly associated loci, including seven near established circadian genes (rs12736689 near RGS16, P=7.0 × 10−18; rs9479402 near VIP, P=3.9 × 10−11; rs55694368 near PER2, P=2.6 × 10−9; rs35833281 near HCRTR2, P=3.7 × 10−9; rs11545787 near RASD1, P=1.4 × 10−8; rs11121022 near PER3, P=2.0 × 10−8; rs9565309 near FBXL3, P=3.5 × 10−8. Circadian and phototransduction pathways are enriched in our
